Abstract: A method of forming an isocyanate-functional polymer component includes forming a first mixture by mixing a recycled polyurethane article and a first isocyanate component having isocyanate-functional groups. The first mixture is heated to a temperature sufficient to transform the recycled polyurethane article from a solid form to a liquid form and react the liquid recycled polyurethane component with the first isocyanate component to form an isocyanate-functional polymer component having an isocyanate-functional group content greater than zero and less than isocyanate-functional group content of the first isocyanate component. The formed isocyanate-functional polymer component may then be used for forming a polyurethane article or polyurethane foam article that is the reaction product of the formed isocyanate-functional polymer component, a second isocyanate component and an isocyanate-reactive component having hydroxyl-functional groups.

Abstract: A flexible polyurethane foam article exhibiting flame resistance comprises the reaction product of an isocyanate and an isocyanate-reactive component comprising a polyol reactive with the isocyanate. The isocyanate and the isocyanate-reactive component are reacted in the presence of a blowing agent and a phospholene oxide. A method of producing the flexible polyurethane foam article includes the step of reacting the isocyanate and the isocyanate-reactive component in the presence of the blowing agent and an effective amount of the phospholene oxide to form the flexible polyurethane foam article which is flame resistant.
